List extracurricular activity?

I started a club at school, and although we did accomplish some stuff, I did not put in a lot of time into it.
So, I want to leave the EC off of my Common App.
However, the teacher I am getting a rec letter from is the sponsor for the club, so I am sure she will mention it in the letter.

So, what should I do? Should I list the EC, or ask my teacher if he will exclude it from the rec letter?

Don’t list it if it wasn’t a major activity for you, especially if you have enough other stuff that reflects your focus.

If your teacher mentions it, that will just look all the more impressive.

Not a problem if your EC list doesn’t include every single thing you’ve ever done - so if your teacher mentions an activity that isn’t there, I agree with renaissancedad that it won’t be an issue.

There is a limited space. Use it wisely.

Ok great thank you! I will exclude it from the Common App then.
